A few weeks back my dad came and visited. He brought a 54cal 700 MLS down that he picked up cheap. I put our 209 conversion on it and we went to the range. While sighting it in, I decided to use up a few of the older CCI 209M (magnum) primers I had. I handed him my phone as I knew I could get a bit better quality video than my last attempt at a video (last time I was alone with an old camera and a tripod).

I knew I'd have a few stuck primers, especially at light loads (80 Gr by vol of Blackhorn209), but figure I want to be straight and put this kit out warts and all (though these really aren't warts... if you go light with the wrong primers they may stick..) But I wanted to be straight up with the performance: zero blow back, and solid ignition, even with Blackhorn209 is easy. If you get a stuck primer, just dry fire. I use standard CCI's with zero stuck at all normal powder charges.

Anyways it shot OK... about 3" at 100 yds with zero load development.

The video below was my first attempt at making a YouTube video... in it I use my Badger Ridge 209 Converted 50 Cal rifle, 120 Gr by volume of Blackhorn209, 240 Gr. 44 cal Hornady XTP's, green sabots and CCI standard primers. Not one stuck primer and zero blow back as well.
